Mark David Quinn (born May 21, 1974) is an American former Major League Baseball outfielder and right-handed batter who played for the Kansas City Royals and former coach for the Baltimore Orioles.

In 1998, Quinn led the Texas League in batting average when he hit .349 for the Wichita Wranglers.

His production at the plate dropped to 17 homers and a .269 average due to nagging hamstring injuries.

The 2002 campaign was plagued by injuries that forced Quinn to spend 156 total days on the injured list that season.

Following his release, Quinn played in the San Diego Padres, Tampa Bay Devil Rays, St. Louis Cardinals, and Chicago White Sox organizations, along with a stint with the Long Beach Armada of the independent Golden Baseball League, but was never able to return to the major leagues.
